Natural supplements are widely used by the American public but, while claim
s of their therapeutic effects abound, medical research does not always sup
port their effectiveness. Clinical trials using Q(10) for the management of
congestive heart failure have had conflicting results; hawthorn is prescri
bed in Germany for the treatment of this condition, but no trials have been
conducted in the United States. Although initial research about the use of
garlic in the management of hypercholesterolemia was encouraging, follow-u
p studies have failed to verify these results. Substituting soy protein for
high-fat animal protein diets, however, does have a beneficial effect on s
erum lipid levels. So far, cholestin (a natural product containing several
statins) has proved to be a cost-saving lipid-lowering medication, and fenu
greek may offer modest improvement as well. Gugulipid is also promising but
requires further research.
